Integrated 32-Point Digital I/O for Cost & Space Savings:Built-in 16 digital inputs + 16 transistor PNP outputs—eliminates the need for additional I/O modules in most small machine applications, reducing system cost and panel space.
Built-in 4-Channel Configurable Analog Inputs:Supports 0–10 V or 0/4–20 mA signals, directly connecting common sensors (temperature, pressure, level)—reduces need for external analog modules and improves system integration.
Dual Communication Ports with Industry-Standard Protocols:Equipped with Ethernet + RS-485, supporting Modbus TCP, Modbus RTU, CANopen Master, and optional EtherNet/IP—enables seamless integration with HMIs, drives, SCADA, and other devices.
Onboard 3-Line Text Display & Navigation Buttons:Features a 3-line LCD display and 5 navigation keys, allowing local monitoring, parameter setting, and diagnostics without an external HMI—greatly improving commissioning and maintenance efficiency.
Expandable with Up to 7 TM2 I/O Modules:Supports up to 7 TM2 series expansion modules on the right side, enabling flexible I/O expansion to meet evolving application requirements.
Industrial-Grade Wide Operating Temperature:Operates from -25°C to +60°C, certified to CE, UL, GL—designed for harsh environments including high temperature, humidity, and EMI, ensuring long-term reliability.
